Yes. A light is not a universal measure of every lint location, and some combined machines use different maintenance arrangements altogether. The absence of a reminder does not replace the manual's routine.
Understanding this situation
Fibres can be visible on accessible seals or transferred from a previous load without triggering a specific warning. Do not assume that all machines have a sensor monitoring every owner-cleanable surface.
A useful next step
Follow the prescribed care schedule and inspect only permitted areas. If lint is excessive, record the textiles and any changed drying result. Avoid dismantling hidden airways because a reminder has not appeared; that work requires appropriate assessment.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
